An object of the present invention is to provide a method for the preparation of geometrical isomers which are important as constituents of synthetic pheromones, synthetic perfumes, terpenes and the like (i.e., a method for the isomerization of cis-alkenyl compounds to their trans-isomers). In this method, the above-described object is accomplished by reacting a cis-alkenyl compound in the presence of nitric acid used as the sole catalyst.
本发明的目的是提供一种制备几何异构体的方法,这种异构体是合成信息素、合成香水、萜烯等的重要成分(即顺式烯基化合物异构化为反式异构体的方法)。在该方法中,顺式烯基化合物在硝酸作为唯一催化剂的存在下发生反应,从而达到上述目的。
